Product Overview
Engineered for fluid transfer in commercial heating circuits and cooling installations, the Grundfos MAGNA3 65 120 F canned-rotor circulator pump operates without mechanical shaft seals. Featuring an integrated control panel, it uses a glandless canned-rotor structure. Applications include mixing loops, heating surfaces, air conditioning, and ground-source loops, via DIN DN 65 ports.
Hydraulic performance delivers a maximum head of 12.0 meters and a maximum flow rate of 429.3 L/Min, matching 25.76 m3/h. Powered by a permanent-magnet motor, the unit operates on a 240 V single-phase supply at 50/60 Hz, with power input P1 of 763 W and current draw of 3.45 Amps. Maximum system operating pressure is rated at 10 bar.
Housing construction features a cast iron casing grade EN 1561 EN-GJL-200 enclosing a composite impeller. Internal components incorporate a carbon-fibre rotor can, stainless steel rotor cladding, and bearing plate, running on ceramic bearings. Net weight is 21.5 kg with a 340 mm port length, handling liquid temperatures -10 to 110 °C.
Control features include AUTOADAPT and FLOWADAPT operating modes with integrated differential pressure and temperature sensors. Wireless communication connects via Bluetooth to Grundfos GO Remote software for diagnostics. External interfaces provide two digital inputs, two signal relays, and a 0-10V analog input.

What fluid temperature limits and immersion depths are rated for this unit?
Fluid media ranging up to 10°C can be circulated through the Grundfos MAGNA3 65-120-F without thermal breakdown.
What peak dynamic elevation does this pump develop?
To overcome vertical elevation resistance, the MAGNA3 65-120-F develops a maximum pumping head of approximately 12 m.
How much water volume can this unit move through the pipework?
At full operating capacity, the MAGNA3-65-120-F moves up to 429.3 L/Min through a DN 65 connection to keep liquid levels controlled during peak inflow.
How is the pump casing constructed to resist mechanical and fluid wear?
Structural defense on the MAGNA3 65 120 F is provided by a rugged Cast Iron casing designed to withstand heavy mechanical stress.
Does this pump run on standard household power or three-phase power?
Running on 240 V power supplies, the MAGNA3/65/120/F is driven by a 0.76 kW motor rated at 3.45 Amps.
